Today, there are a lot of improvements that can be done to roofs to make them more energy efficient. When doing renovations and new construction, there are also green building certifications that can improve the value of a property and help save energy at the same time. If you want to get green building certifications, you will want to consider the type of roofing materials you use. The following tips will help you choose the best combination of roofing materials and improvements to receive the green building certifications you are trying to get.
Attic Insulation and Roof Design
The insulation of your attic is important if you are trying to get a green building certification. When doing the improvements to the roof, you will want to consider modern attic insulation improvements like spray foam. Make sure that the attic has a good R-value to stop thermal transfer, but do not forget about enough ventilation to allow heat to escape and to prevent problems with moisture damage.
Energy-Efficient Roof Underlayments
Thermal transfer is a major cause of energy waste in modern building designs that you will need to deal with to get a green building certification. When installing new roofing, you will want to consider upgrades to the roof decking and moisture barrier materials. Use materials like foil-backed plywood and synthetic moisture barriers to make your roof more efficient and improve the chances of getting your green building certification.
Environmentally Friendly Renewable Energy
Renewable energy like solar energy can be a great addition to a greener building design. First, you may want to consider installing solar roofing materials that can help produce electricity for the needs of electrical outlets and common appliances. In addition, there are options for solar-thermal collectors that can provide energy to water heaters and building HVAC systems, as well as other mechanical systems.
The roofing materials are probably one of the most important choices for an energy efficient building design. Common asphalt shingles cause heat gain and energy loss. Today, there are modern options like synthetic materials that reduce thermal transfer. In addition, there are options for cool roof designs with lighter-colored materials and coatings to help protect buildings from heat gain and thermal transfer.
These are some tips to help you choose the best combination of materials and improvements to your roof so you can get a green building certification. If you are doing renovations or other construction projects, contact a roofing contractor and talk to them about some of these options for your project.
